To all whom it may concern:

Be it known that I, HAROLD D. Cannon, a citizen of the United States7 and residnt of Detroit, lVayne county, Statev of Michigan, have invented certain new and useful Improvements ,in' Motor-Vehicles, of which the following is a specification.

This invention relates to motor Vehicles and particularly to motor truck cial vehicle construction; I

Strength, durability and cheapness of manufacture are among the points aimed at byV the commercial vehicle engineer. A simple construction that lends itself well to manufacture is the construction sought -in The present invention is an improvement upon previous truck constructions and is novel particularly One of the objects of this 'i'nvention is to provide a vehicle comprising a frame andl axl'e, with suitable side or longitudinal Springs and a transverse auxiliary .spring which is adaptedr'to assist in sustaining an overload and in checking the rebound of the frame or truck body caused by passing over irregularities .in the roadbed. This, and other objects of the' invention, are apparent from the detailed description taken in connection with the drawings which form a part of this application, and in which- Figure 1 is a' side elevation and part longitudirml sectional view. of the rear portionof a motor truck, the section being substani tially on the line 1-1 of IFig. 2; Fig. 2 is a rear elevation of9 and part transverse sectional lview through, the" vehicle shown in Fig. 1; and Fig. 3 is aview similar to Fig. 2 with the frame and axle; in difi'erent relative positions. 1

Referring to the drawings, 10 represents the two side members of ithe vehicle frame and 11 isy` one of the cross members which is v shownhs being of I-bea 'construction and connecting the side members. ther cross members may be cmployed as desired to give the frame proper strength. The cross memher '11 is arranged directly over the vehicle rear hr driving axle 12, on the outer ends of which `are the Wheels 13 which support one end of the vehicle. x

The Wheels may be driven through. any suitable driving mechanism such as the gearing contained in the gear box 14:, and the axle is properly positioned relative to the 01' COInIIleI'- in its practical manufacturing advantagesspecification of Letters Patent.

frame by means of radius rods 15 which may be adjustable.

Each of the side'members 10 is provided with a pair of brackets 16 properly secured thereto and arranged substantially equidistant fore-and-aft of the axle and the cross member 11. Side Springs 17 are secured to suitable seats 18 on the axle 12 by means'of spring clips 19. The free ends of the Springs 11 angage the under sides of the brackets 16 an but which comes into operation when the veare arranged to slide thereon as the, frame moves relative to the axle, as will be hiole is loaded beyond a given amount. In i the present invention this auxiliary spring is 1 n` the form of a transverse leaf spring which is reinforced both above and below 'so that it will take'the overload on the rebound as will be more fully hereinafter de-` scribed. ;This auxiliary transverse spring 22 is secured to a seat 23 on the under side of the cross member 11 by means of spring clips 2-1 which pass through holes in both of the fianges 25 of the I-beam cross member. This makes a very secure construction for the auxiliary spring 22 and places the nuts for i the spring clips in an accessible position 'so that they may easily be kept tight.

i Normally the spring 22 is inactive as shown in full lines in Fig. 2 but when' the vehicle is loaded beyond a given amount the sprirual comes' into action by its ends engagrlng the Springs 17 at their centers where they are secured to the axle as shown pari ticularly in Fig. 3. Upon the rcbo'und of the frame relative to the axle the parts are,

in' the position shown in the dotted lines in Fig. 2., in which it will be seen that the extreme outer ends of the Springs 22 engage' under brackets 26 which 'are secured tothe o axle 12. These brackets `l26 are of inverted U-shape .as shown particularly in Fig. 1 and they are forme'd with inturncd ends .21, which are arrenged' to hoolrunder lugs2'8 formed integral with the exle 12 just'l outboard from the spring'seats 18. These ends 1th vthe rebound lstrainsare not taken by the bolts themselves butby the'inturned ends 27.

It will also be seen that the spring 22 engages the brackets 26 at points beyond its engagement With the Springs 17 so that greater resiliency is obtained from Sprin 22 on the rebound than on zthe overload. lso Where the frame members 10 are located (n; rectly over thefsprings 17, the Springs 22 may be given a wider range of-action by arranging the brackets 26 outside of spring 17 than as if they Were located between the spring 17 and; the frame.

It isbelieved* that the operation of the structure is plainfrom the above description and the drawin's; I s i i f'I-Iaving thus described my invention What I claim and desire tosecure by LettersPattent is: 1. In a vehicle, 'the combination with the frame, the axle, andthe Side Springs-"of an auxiliary spring secured to the frame and.

adapted to engage the axle as the frame moves downwardly, and a bracket adapted a tovengage said auxiliary spring on' the re-` bound at a point more remote fromthe` cenment wjith the axle.

'ter ofthe spring than its 'point of engage'- anxiliary-spring secured to the frame and 'adapted to 'engage the axle as the frame v'move's downwa'rdly, and a bracket secured w to the axle.. ;nd1adapted to engage said auxliliaryisp'ring;onf'thelrebound at a point more remote frornthe'cfenter of the spring'than :its point of eng'a'gment with the axlei" 1 3. In'a vehicle, ythe combination'wi'tkthe frami, the axlean'd the-side Springs, lof an auxilhry spring secured to.th,e frame and,
